(Just over) a week with the Fitbit Charge HR

Over the last couple of months I’ve attended a couple of British Computer Society (BCS) meetings on the “Internet of Everything”. Looking at the speaker’s activity band got me thinking about “the quantified self”. Just as, when I’m cycling or running, I like to track my activities and see how I’ve done compared with others, this year I decided to buy myself a fitness tracker. I’ve worn pedometers before (when taking part in the Global Corporate Challenge) but with the current (and upcoming) range of activity bands/watches, my device of choice is a Fitbit Charge HR.

Why the Fitbit Charge HR? Well, I’d seen the Charge and it looks good – discrete, but functional – and the additional £20 for heart rate readings sounded interesting (and should lead to more accurate calorie counting).  There are Apple and Microsoft watches on the way but I’ve been burned far to many times buying a first generation product (iPad, Nokia Lumia 800) and Fitbit have been working in this market for a while now – their trackers are pretty well established. I was also seeing some good reviews on the Charge including this one from Michael d’Estries (@michaeldestries).

Setup

The setup was simple – the product packaging directed me to a website to download and install the software on a PC (or Mac in my case), together with a dongle after which the band updated itself and continued to sync. There’s also an app on my phone that communicates via Bluetooth (I use this for call notifications and synchronisation). I’m not sure what technology the dongle uses (ANT+ perhaps?) but it’s certainly not the Mac’s built-in Bluetooth stack.  I also need to work out why, since I paired the band with the app on my phone, the Mac no longer sees it as present but that’s not stopping me from using it so can wait a while.

Charging

Next up was charging the battery. It had some power out of the box but needed charging soon after (unsurprisingly).  Fitbit’s claimed battery life is 5 days but I’d say it’s nearer to 2-3. Actually, I don’t let it run down that far – I generally charge daily – and I started off by charging whilst taking a shower, etc. as any steps taken during the period are probably balanced out by steps recorded as a result of movement during sleep.  Unfortunately, putting it on charge when I woke (and before it had registered much activity confused the sleep tracking (it thought I was still asleep!) so I’ve since started to charge it whilst sitting at my desk, working at a PC.  It really does seems like this would be one device that really would benefit from wireless charging!  Added to that, the proprietary connector locks on well but I can’t help thinking it’s another way to make money (replacing lost/broken cables) and micro USB would do the job just as well?

Monitoring steps, hear trate and sleep

Importantly, the step count seems reasonably accurate. There are some phantom steps when driving/otherwise moving my wrist but the Charge HR basically seems to keep time with walking (goodness knows how as it’s nothing to do with how I swing my arms or not!).  Incidentally, you can’t delete/edit the recorded steps/floors data so it’s worth logging driving as an activity (take a note of the start and finish times) to negate the entries as it’s somewhat disconcerting to be notified that you reached your step target whilst driving along the motorway!  Unfortunately, although recording an activity trues up the step count and other metrics, any badges earned remain on your profile.

I’ve yet to check the heart rate monitoring compared with the Garmin chest band that I wear on my longer bike rides – it seems a little low to me but maybe a bike ride is more exerting than I think!  And on the subject of exertion, I was amused to see that, one evening, after visiting my local pub, the walk back up the hill counted as both active minutes (raised heart rate) and towards the number of stairs climbed (due to the elevation)!  Stair climbing (along with distance walked, when many of the steps are around the home/office) seems a bit of a gimmick but still another metric to compare. It’s not 100% accurate, because Fitbit measures a flight of stairs as 10′ elevation (based on atmospheric pressure) – modern homes may be less than this, and commercial buildings more – but it’s there or thereabouts.

Sleep tracking is another reason I was interested in wearing a band, which is also the reason I can’t charge at night (as I do my phones). I’m not sure exactly how this works (it tracks time in bed, restlessness, and time awake) but I’m pretty sure “time reading a book before going to sleep” gets recorded as sleep (perhaps the low heart rate?), as does “lying in bed being lazy (a lie in)”. As mentioned previously, so does taking off my watch and pugging it in to charge after sleep as the software only seems to end the sleep when I’m active – and therefore starting to charge it whilst I’m still in bed extends the sleep time!

Some niggles

There are some minor niggles to watch for:

  • The Charge HR has a proper strap buckle (the Charge has a different clasp) and it can be tricky to get the correct adjustment (not too tight, not too loose for HR monitoring); however I haven’t worn a watch for many years so it may just be me getting used to having something on my wrist again.  More significantly, the strap is quite short (even the large version). Mine only has about another centimetre of expansion and, whilst I’m a stocky guy, I’m not huge – I’m sure there are others with bigger wrists than mine.
  • The watch face appears to be plastic rather than glass and I was disappointed to see it had scratched after a few days of use, although I was shown a Microsoft Band a few days ago and that was clearly scratched (on a much larger screen). I guess I’ve been spoiled by glass smartphone screens and expect the same from all devices…
  • If you’re in the UK, Fitbit’s food record database is terrible. So far the only items recognised by the barcode scanner in the app have been from Costco (i.e. American products) and I’ve used other apps that do a much better job for this. Also, the Fitbit food tracker can’t create recipes (i.e. add a bunch of ingredients, save as a recipe with x portions, then eat y portions). After a few days, my common food items have mostly been added manually (which has taken quite a lot of time) but there’s still the issue of tracking food when eating out. Maybe it’s pedantic but it does seem to me to have little value in accurately tracking calories burned if I don’t accurately track calories eaten…
  • As with driving, when logging activities (exercise), be ready for some inaccuracy as (unless logged as a walk/run, etc. via the Fitbit app) because manually-logged activities can be recorded down to the second on duration but only to the minute on start/end times! So, if I take an activity from Strava (for example) that started at 16:39 and lasted 18m 11s… the heart rate graphs don’t quite match up. As you can’t edit an activity (only delete and re-record), it can take some trial and error to record it accurately.

App ecosystem

In general, activity tracking would actually be greatly improved if there was broader integration between apps (e.g. Strava-Fitbit or Garmin-Fitbit). There is an ecosystem of Fitbit-aware apps but we’re a long way from a universal health tracking app ecosystem. Added to that, the need for premium versions of each app, with subscriptions in order to integrate (e.g. MyNetDiary-Fitbit) could get expensive.  I’m hopeful that Apple, Microsoft et al will make great strides in this area (and I’ve linked my Fitbit account to Microsoft HealthVault) and it’s certainly something to watch over the next couple of years.

Conclusion

So, it seems that health tracking is useful, but I need to modify the way I work to deal with the Fitbit Charge HR’s shortcomings re: charging, sleep monitoring, food diaries, etc. I’m still really pleased with mine (and don’t think any other device would be any better, right now) but it’s not quite the put-it-on-and-ignore-it sensor I’d hoped to accurately quantify myself with! Maybe my expectations were just a little too high…

I bought my Fitbit Charge HR Heart Rate and Activity Wristband from Amazon UK.

Short takes: Shrinking Outlook OSTs; locating and removing “stale” Yammer users; editing GPS tracks

Some more snippets of blog posts…

Reducing the size of your Outlook offline store

Tim Anderson commented recently that he’d noticed how recreating his Outlook offline store (.OST) file was more effective than compressing it.  I decided to give mine a go (especially as my recently shrunken Inbox means there wouldn’t be much to re-sync).

Unfortunately, my IT admins appear to have locked down my configuration via group policy so I couldn’t disable/re-enable cached mode. @p3rfact came up with a suggestion that worked though:

As it happens, my file was not that large – although recreating it did reduce the size by around 25%.

Clearing out users from Yammer

Yammer  networks can be synchronised with Active Directory using Yammer Directory Sync but ours is not (for various reasons). There is a pretty simple workaround though for clearing out users from Yammer who have left the company (credit due to @AlanPurchase for working this one out):

  1. From the Network Admin view in Yammer, export a .CSV file with all the users in the network.
  2. Open the .CSV file in Excel and filter on the state field to show active users and on the email field to include domains that you are interested in (for example, I only wanted those in our UK organisation).
  3. Cut and paste email addresses into a new email in Outlook, then use Ctrl+K to resolve the names against the Global Address List. Anyone that isn’t in the GAL will not have their email address resolved.
  4. In Yammer, remove each of the users that are no longer in the organisation – you have the option to remove their posts or leave their posts and remove the account (more details in Microsoft knowledge base article 2820235).

GPS Track Editing

I’ve blogged before about how I log all of my bike rides, runs, etc. – it’s sad, but I like to see where I went on a map – and to know how I performed. Every once on a while, things go wrong though – like one time last summer when my Garmin suddenly decided I was several miles away and the route I was following became nonsense. The only answer was to reset the thing and start tracking again (breaking my ride into multiple tracks).

I found a free GPS Track Editor that helped me to merge/edit tracks (directly editing the XML in GPX files is a chore) and create something that at least represented the route I was on (although it does have one section that is a dead straight line “joining the gap” between my two usable tracks – it should actually follow the road via Whittlebury)!

Technology Waffle and randomness

A manifesto for improved use of email

Email. A critical business communication tool: ubiquitous in its use; with global reach – it’s clear to see how the benefits of improved, anytime, anywhere communication have broken down barriers and created efficiencies. But has email reached a tipping point – where the volume of messages and the need to respond have changed the focus from email as a tool that helps us to perform our work to one where email has become the work itself?

The problem of email overload has led some people to call for “no email days”, or to consider the “email rapture” (i.e. what would we do if email suddenly didn’t exist) and some organisations (most famously Atos) have initiated programmes to reduce or remove the use of internal email, using evocative terms like “information pollution”. (Forrester Analyst Philipp Karcher has an interesting view on this too.)  Others have targeted other drains on productivity (e.g. Coca Cola’s crackdown on voicemail) but it’s clear that there is a huge hidden cost associated with unproductivity in the way we communicate in the workplace.

I became an “email bankrupt” recently where, on return from the Christmas holidays, I processed the new items in my Inbox and moved everything else to an archive – starting a new year fresh with a new (empty) Inbox and vowing to stay on top of it (tidy Inbox… tidy mind).  Many of the archived messages were over a year old and whilst I intended to take action on them, there just wasn’t enough time in the day.  Mine is not an isolated case though – there are many stories on the Internet of those who have found it cathartic to start afresh – and many more with suggestions for keeping on top of things. Some ideas have gained traction, like the Inbox Zero approach evangelised by Merlin Mann or Scott Hanselman’s Outlook rules for processing email but the problem was perfectly summed up for me late in 2014 when I saw Matthew Inman’s cartoon depicting email as a monster that craves attention.

A cultural issue?

Many of the issues associated with email are cultural – in that it’s not the technology that’s at fault, but the way that people use it. For example, email is an asynchronous communication mechanism – i.e. the sender and recipient do not both need to be online at the same time for the message to be sent and received; however many email users seem to expect an immediate, or at least rapid response to email.  Multiply this by many tens or hundreds of emails sent/received a day – and their replies (possibly in various threads as people are copied or dropped from the distribution) – the resulting volumes of email become significant, as does the effort required to process it.  Consider the cost of this email mountain and the numbers are staggering (one infographic estimates the cost of processing email in North America alone to be around $1.7 trillion) – so anything that can be done to reduce the volume of email has to be positive.

In an age of smartphones and mobile communications, out of office messages may seem a little quaint (although we all need to take holidays – and that should include a break from business communications – although that’s a topic worthy of its own discussion) but the need to say “I’m travelling so my response may be delayed” is indicative of an organisation whose culture expects emails to be answered quickly – and where email is used as a task manager, rather than an information-sharing and collaboration tool. Not that there’s anything wrong with using email as a task manager within a workflow system – that’s a perfectly valid use of the technology – but when knowledge workers send an email asking someone to do something (often without context) as if it somehow absolves them of responsibility for a task and passes the baton to another, email becomes a giant “to do list” over which the owner has no control!

Paradoxically, the rapid response to email (fuelled by notifications each time a new one arrives) is feeding the email habits of others – if your colleagues are used to receiving rapid responses, late night replies, etc. to their emails then you make the problem worse by continuing to respond in that manner – a conditioned reflex which could be thought of as “Pavlov’s Inbox” (credit is due to Matt Ballantine for that observation).

Time for change – an email manifesto

In the 1990s, as email was rolled out to large populations in government and commercial organisations, it was common practice to include training on email etiquette. Back then, the focus was on use of informal language for business communication and the implications of emailing other organisations, forwarding/replying/replying to all/copying, capital letters (shouting), emoticons, etc. but maybe we’ve reached a point where we need another round of cultural change – a new email etiquette for 2015 – an email manifesto?

  1. Email should only be used where appropriate. If an immediate/rapid response is required, consider alternatives such as instant messaging, or a phone call. Save email for communications that are not time-sensitive. Use other systems (e.g. enterprise social media platforms and RSS-based newsfeeds) for collaboration/knowledge sharing.
  2. Emails should include a clear call to action. If it’s not clear what is being asked, you’re unlikely to achieve the desired outcome.
  3. Email sent does not equal action taken. Consider that emails may not be received, may not be read, or may be ignored. Just because something is a priority to one person, department, or company doesn’t mean it is to another and, if you need someone to do something, make sure they are on-board and ready to work with you. If you don’t hear back, follow up later – but consider using another method of communication.
  4. Carbon copy (CC) or blind carbon copy (BCC) means “for information”. If you expect someone to take action (see previous point), make sure they are on the “To” line.
  5. The subject heading must be relevant to the content of the email. Topics sometimes branch off in new directions as the conversation develops and if someone new is brought in to the discussion then it really helps to have a relevant subject line!
  6. Keep it brief (but not too brief). Emails should be concise – a couple of paragraphs – any more and it won’t be read. If you have to spell things out in more detail use bullets, etc. but consider the reader – they might be reading the message on a mobile device and if you make it easy to understand you’re more likely to get a positive response.
  7. Check your email before you send it. Brevity is good but does your message make sense? All too often one line responses require the recipient to decipher ambiguity or read through pages and pages of message history to understand the context.
  8. Check calendars when scheduling meetings. This is only tangentially related but, if the email system includes calendar functionality, take the time to check availability before sending a meeting request. It may be the best time for you – but is everyone else free? On a related note, emails to groups of people asking “when’s best for a meeting” are a waste of everyone’s time – use the calendar scheduling tools!
  9. Consider the cost of email. Not the cost of running the systems but of continually checking email. Multitasking is a myth. Turn off email notifications and try to get out of the habit of glancing at your smartphone in meetings. Focus on one thing at a time and do that thing well. Think before you send email and consider that every email costs money and time!

Moving on from an #HourOfCode to 20 hours of code…

A couple of weeks ago, I wrote about the Hour of Code events that are running as part of Computer Science Education Week and, last Thursday, I took my 10 year-old son to our local Apple Store to take part in an event. Unfortunately his younger brother wasn’t interested (“I don’t really like programming” was the response) but I’m not going to push it – not everyone likes the same things and I do at least know he’ll be exposed to some coding at school (Scratch was part of the ICT curriculum at their school, even before the recent shake-up in computer science education here in the UK).

Using a Scratch-like user interface, the Hour of Code used a sequence of puzzles to guide Angry Birds through a route to find some pigs, the Zombies and Plants, and Squirrels and Acorns… with the opportunity to view the resulting JavaScript code at each stage.  Working up from simple steps forward/turns to repeat [for] loops, repeat until [while] loops, if statements and if/else statements it was great to see my son asking “what are all the funny brackets” when he viewed the code (and equally great to be able to use some of the C he’s tweaked with the Arduino as an example of passing parameters).

At the end of the session we were pointed at another twenty hours of code available at the code.org studio, allowing kids (and adults) to build up confidence and knowledge of basic computer science principles but the real buzz for me was seeing my son’s browsing history the next morning, spotting the Google search for “20 hours of code” and the fact he’d got stuck in to some of the puzzles to create his own game without any nudging from his geek father. That put a big smile on my face.

Reconfiguring a PlusNet ADSL router (Technicolor TG582n)

This post is probably not much interest to many people but it might help some if, like me, you’re trying to re-configure a Technicolor TG582n ADSL router from PlusNet. Just make sure you read all the way to the end and save yourself some time!

For the last 11 years, my ADSL connection has been running with an elderly Solwise SAR110 ADSL modem/router, provided by PlusNet when we first connected to 512Mbps ADSL. Those were the days – half a meg download speeds seemed so fast back then! Whilst fibre has (just about) reached my neck of the woods, my ADSL 2 connection is working well, most of the time, and I get about 6Mbps down and 0.7Mbps up these days. Indeed, the connection actually seems to have become more responsive lately (my theory is that the contention rate has dropped in line with people switching to fibre)!  I did have cause to call PlusNet for support last week though, and they agreed to ship me a new router if I signed up to one of their current packages (which, incidentally saved me money too as we were still on a very old tariff).

The new router is a Technicolor TG582n and I finally got around to setting it up tonight. I was told that I might get slightly faster speeds but there’s no evidence of that based on the tests I’ve run so far (that may change in a couple of days when we roll into a new billing month and onto the new service) [Update: after a few reboots my speed has doubled to around 12Mbps]. For now though I just want to swap the old router out for the new one.

The first thing I found was that the default configuration sets the router’s IP address to 192.168.1.254. That’s the IP address of my wireless access point, and all of my devices are expecting a gateway address of 192.168.1.1.  So, I downloaded the router configuration (Technicolor Gateway -> Configuration -> Save or Restore Configuration).  This gave me a file called user.ini, which I then searched for all instances of 254 and looked like they were part of an IP address (ignoring one which was part of a long string of numbers) and replaced 254 with 1.  I then uploaded the new configuration and, hey presto, the browser refreshed giving me back the config for my wireless access point on 192.168.1.254 and the router was responding on 192.168.1.1.  That seems a bit of a kludge and there should be another way to do this, but I couldn’t find it in the GUI (at least not with software release 10.2.2.B).

Then, reading around I found that the router also has a DHCP server enabled by default. I don’t want that right now (my Raspberry Pi is doing that job for me) so I started to investigate switching that feature off. Again, I couldn’t find it in the GUI, so I tracked down a copy of the CLI guide for the router (from another ISP – Demon – albeit for an older release) and, sure enough, after telnetting onto the box the dhcp server config command told me it was enabled so I corrected that with the following commands:

dhcp server config state=disabled
saveall

After all that, I found the config that I needed – it seems that the location to make the changes is Home Network -> Interfaces -> Local Network -> Configure.

There I found some handy checkboxes to turn on/off DHCP servers (IPv4 and IPv6) as well as the static address for IPv4 addresses!

After all this, I may well switch over to one of the popular open source firmware packages on the router… but I’ll leave it alone for now…

Learn the basics of computer programming in an #HourOfCode

Next week (8-14 December 2014) is Computer Science Education Week and the Hour of Code is coming to the UK. More than 3 million people have tried an Hour of Code already, in an initiative that aims to dispel any myths that computer programming is difficult and to provide parents, teachers and students across the nation with an enjoyable introduction to coding. Code.org hope that this will help build awareness of and confidence in the changes that have come in the September 2014 English school curriculum.

It’s not just in schools either – my employer has 24 “hour of code” workshops scheduled all over the country for our technical staff to give non-techies a one-hour introduction to the basics of computer programming and there’s been a fantastic sign-up rate.

Other IT companies are getting involved too (actually, there’s an extensive list of partners) including Apple, who are hosting Hour of Code workshops in Apple Stores across the world on 11 December (I’m hoping to get at least one of my sons to come along with me). It’s billed as “no experience needed” and for “ages 6-106″.

If computer programming is a mystery to you but it might be something of interest, find out more about the hour of code on the Code.org UK website or follow @codeorg on Twitter.

And if the Hour of Code whets your appetite, you might like to check out some of these resources:

Short takes: Unicode characters in Windows; OS X Remote Disc goes AWOL

More micro-posts from the collection of open tabs in my browser…

Unicode characters in Windows

Sometimes, when tweeting, it’s useful to be able to type the unicode horizontal ellipsis (…) rather than three full stops (…). It might look similar, but that’s two less characters out of 140.  I remember back in early days of Windows I could enter special characters using the numeric keypad but it seems that still works (sort of): FireFormat.Info has some useful information on entering Unicode characters in Microsoft Windows.

Mac OS X Remote Disc goes AWOL whilst installing Adobe Lightroom

My new Mac Mini doesn’t have an optical drive. That’s not generally a problem except I needed to install Lightroom on it, so I used OS X’s Remote Disc technology to share the DVD drive from my old MacBook across the network.  The software installation was progressing nicely until, right at the end, the Adobe installer wanted me to insert the disc! As I was already connected to a logical disc, I had no way forward but to abandon the installation, connect a USB DVD drive and try again.  Seems it’s not the universal solution to accessing optical media that I had hoped…

To add insult to injury, I then found (thanks to the Lightroom Queen) that the Lightroom downloads on the Adobe website are the full programme, so I could have downloaded the software and installed it locally – all I really needed was my license key!

Choosing an Office 365 identity model (when to use ADFS)

At the time of writing, Microsoft Office 365 has the ability to work with three identity models:

  • Cloud identity (stored in Microsoft Azure Active Directory).
  • Synchronised identity (a copy of the objects from an on-premises Active Directory is made in Microsoft Azure AD), optionally with synchronised password hashes.  This is also known as same sign on (not single sign on as there are still two separate objects, albeit two objects that are kept synchronised).
  • Federated identity, using a federation service (such as Active Directory Federation Services, but others are supported) to authenticate users in an on-premises directory following which authorisation can be granted to Office 365 resources. This is also known as single sign on.  In this instance, directory synchronisation is still used to populate the Azure AD with user objects, although authentication happens on-premises.

Whilst the majority of small businesses will be fine with cloud identities, many of my conversations with enterprise customers start off in the directory synchronisation space. Generally, synchronisation is performed using the Office 365 DirSync appliance (a customised version of Forefront Identity Manager) although, more recently a new tool (Azure AD Sync) has been released that will eventually replace DirSync.  At the time of writing the main difference is that Azure AD Sync supports multiple forests (DirSync is a single forest solution) but it doesn’t support password synchronisation (still a major advantage for DirSync).

In general, the approach I recommend is to choose the simplest model for the organisation’s needs. The cloud identity model can work well when there is no on-premises directory service or there is no requirement to integrate; synchronised identity is the most commonly used (assuming there is an existing Active Directory) but sometimes federation is required:

  1. If there is an existing ADFS infrastructure.
  2. If a third party federated ID provider is in use.
  3. If Forefront Identity Manager 2010 is in use (which does not support password synchronisation).
  4. If there are multiple on-premises Active Directory forests (although Azure AD sync may negate this requirement).
  5. If smart cards or other third-party multi-factor authentication solutions are in use (Azure AD does have an MFA capability, although there are some restrictions on its use).
  6. If custom hybrid apps or hybrid search are in use (SharePoint).
  7. If a hybrid Lync solution is in use (i.e. placing users with enterprise voice capabilities on premises and those that don’t need voice in Lync Online, sharing the same SIP namespace).
  8. For self-service password reset via a web service (only administrators have self-service password reset in Office 365).
  9. If there is a requirement to audit logins and/or immediately disable accounts.
  10. If there is a requirement for single sign-on (i.e. accessing Office 365 workloads with the same user credentials as on-premises).
  11. If there is a requirement to restrict client logins by time or location.
  12. If the organisational security policy prevents the synchronisation of password hashes to Azure AD.

On a related topic, the Microsoft Online Services Sign-in Assistant (MOSA) for IT Professionals only exists to simplify the user experience (handling tokens, etc.) and is generally not required with modern versions of Office. Administrators using PowerShell may still need it though.

Finally, if ADFS is down, there is no way for users to authenticate. For that reason, federated infrastructure needs to be highly available (e.g. multiple ADFS proxies and multiple ADFS servers).  One method that’s starting to be commonly recommended is an “ADFS safety net”, using DirSync as a fall back (it’s possible to move between identity models on demand) but obviously that’s only an option if your organisation’s security policy allows the synchronisation of identities (including password hashes to minimise the impact on end users).

For reference, the PowerShell commands are:

Convert-Msol-DomainToStandard -DomainName domainname.tld -SkipUserConversion $true
Convert-Msol-DomainToFederated -DomainName domainname.tld

Set-Msol-DomainAuthentication -Authentication Managed -DomainName domainname.tld
Convert-Msol-DomainToFederated -DomainName domainname.tld

My new Office 365 Resource Centre

I’ve been doing a fair amount of work with Office 365 in recent months (including passing certification exams) and, along the way, I’ve found a lot of snippets of useful information. Normally I’d write a blog post but I expect to be constantly adding to the information so I thought I’d create a different solution this time.

So, I’ve started to create what’s currently known as Mark’s Office 365 Resource Centre. It’s work in progress – and I’m sure the structure will change as it grows over time – but at least I’ve found something to do with the public website on my Office 365 subscription!

Déjà vu: buying and upgrading another Mac Mini

Eight years ago, I was writing blog posts about buying a Mac Mini and upgrading its inner workings. Then, last weekend, I bought a new one.  Well, actually I bought the outgoing model at a knock-down price, thanks to a tip-off from Dom Allen (@ca95014).  A 2.3GHz Core i7 late-2012 model should happily replace my aging MacBook and, unlike the late-2014 model that Apple recently announced, it has upgradable RAM (up to 16GB) rather than memory integrated on the main logic board (I believe the term is planned obsolescence and I find it deeply cynical…).

As usual, I bought my memory from Crucial but, whilst I was waiting for it to arrive, I introduced my eldest son to the Apple unboxing experience…

The memory turned up a day or so later and now I’m in the process of transferring all of my images and photo-editing software to the new Mac… I’m sure there will be more posts to follow on that experience.

With some more hard disk space and a faster Mac, maybe I’ll start taking more pictures (lost my “photo mojo” of late, although I did grab a few shots when I went to watch the Revolution Series track cycling a couple of weeks ago).
